    Jul 26, 2021 While silica sand is one of the most plentiful naturally occurring minerals on the Earth, high grade silica sand is relatively rare and experiencing a booming demand. This is because high purity sand requires very low impurities such as sulphides and iron will that cause imperfections. Demand High-tech applications such as fibre-optics, LCD.Water eluting mud The grade of SiO2 in silica sand decreases with the finer grain size of quartz sand, while the grade of impurity minerals is the opposite. This phenomenon is particularly obvious in silica sand containing a large number of clay minerals, so it is very necessary to wash and desludging the raw quartz sand before being selected.
